Serving Larkspur, CA and surrounding areas. (415) 430-9873
Every deck, addition, and retaining wall starts with what is buried underground. We pour permitted footings sized for Larkspur's clay soils and California's seismic requirements - so the structure above stays level for decades.
Concrete footings in Larkspur involve digging to stable soil, setting steel reinforcement in wood forms, passing a city inspection, and pouring the concrete - most residential footing jobs run one to three days of active work, with a curing period before any structure is built on top.
A footing is the underground base that holds up everything above it - a deck, a fence, an addition, or a foundation wall. You never see it once the job is done, but it is the most important part of any structural project. In Larkspur, where clay-heavy soils move seasonally and seismic requirements call for specific reinforcement, getting the footing right matters more than in many other parts of California.
Homeowners adding a deck or outbuilding often combine footing work with foundation installation when the project scope calls for a full structural base rather than individual post footings alone.
If a deck post is no longer perfectly vertical, or a gap is opening between the deck structure and your home's exterior, the footing below that post may have shifted. In Larkspur's clay-heavy soils, this kind of movement is not unusual after a wet winter followed by a dry summer. A leaning post means the footing is no longer doing its job and the structure above it is at risk.
Horizontal or stair-step cracks near the bottom of a concrete wall, or cracks radiating from the corners of a slab, can signal that the footing underneath has moved or failed. In older Larkspur homes - many built in the 1950s and 1960s - original footings were often shallower than current standards require, making this kind of cracking more common.
Any new structure that attaches to your home or stands independently in your yard will need proper footings before work can begin. Larkspur's building department requires permitted footings for decks, additions, and many fences. If a contractor quotes you on a deck without mentioning footings or permits, that is a red flag worth taking seriously.
When a footing settles unevenly, the structure above shifts slightly - and one of the first signs is doors or windows that suddenly stick, do not latch, or have gaps at the corners that were not there before. This is especially worth noticing in Larkspur homes near hillsides or in areas with known soil movement.
We install concrete footings for decks, room additions, fences, retaining walls, and standalone structures throughout Larkspur and Marin County. Every footing we install is permitted and inspected - the city inspector visits the site before any concrete is poured to confirm depth, dimensions, and steel placement are correct. This is not optional in Larkspur, and any contractor who suggests skipping the inspection is putting your investment and your home's resale value at risk.
Each footing is designed for the site's specific soil conditions. Larkspur's clay-heavy ground requires footings sized to handle the expansion-contraction cycle that runs with the seasons. We also incorporate the steel reinforcement required by California's seismic building standards, since Larkspur sits close to active fault systems and the California Geological Survey maps much of Marin County as an area of elevated seismic hazard.
When a project calls for more than individual post footings, we also install slab foundations for structures that need a continuous base rather than isolated footings at each post location. Both services are permitted through the same City of Larkspur process, and we handle all the paperwork.
Best for homeowners adding or replacing a deck, front porch, or covered entry - individual post footings to the required depth.
Best for room additions, detached garages, or accessory structures that need a permitted foundation before framing begins.
Best for hillside properties in Larkspur where a retaining wall needs a properly sized footing to resist soil pressure and seasonal movement.
Best for older Larkspur homes where original shallow footings have settled, shifted, or no longer meet current seismic standards.
Larkspur has a significant number of homes built in the mid-20th century, many of which were constructed under standards that did not account for today's seismic or soil requirements. If you are adding onto an existing structure or replacing old footings, your contractor may find that the original foundation work does not meet current standards. This is not a contractor upselling you - it is a real condition that comes up frequently in older Marin neighborhoods. Knowing this going in helps you budget realistically and avoid surprises mid-project.
The wet winters here also affect how and when footing work gets scheduled. Larkspur gets roughly 40 inches of rain a year, most of it between November and March, and pouring concrete into waterlogged or muddy soil weakens the mix and can cause uneven settling as the ground dries out. Most experienced local contractors prefer to schedule footing work in the dry season - roughly April through October. The American Concrete Institute provides guidance on how soil moisture and temperature affect concrete performance, and those factors are especially relevant in a Marin County winter.
We work throughout Marin and the wider Bay Area and understand how footing requirements, soil conditions, and permit timelines vary from one community to the next. Homeowners in Mill Valley and San Anselmo deal with similar hillside lots and clay soil challenges, and we handle footing work regularly in both areas. If your property is on one of Larkspur's steeper streets near Baltimore Canyon or in the flatlands near Corte Madera, we know the terrain and what soil conditions to expect.
We visit your property, look at the site, and measure what is needed. We check soil access, look at existing conditions, and ask about the age of your home and any prior work done nearby. We reply within one business day and give you a clear estimate before any commitment.
For most structural footing work in Larkspur, we submit a permit application to the City of Larkspur's Community Development Department before a single shovel goes in the ground. We handle the paperwork and keep you updated on the timeline - permit approval typically takes several days to a few weeks depending on project complexity.
The crew digs the holes or trenches to the required depth, sets the wood forms, and places steel reinforcement inside. This is the noisiest and most disruptive part of the job. Equipment access and parking will be needed, and the work area should be clear of children and pets.
A city inspector visits before any concrete is poured to confirm depth, size, and steel placement. After approval, the concrete is poured, finished, and the forms remain in place while it sets. We remove the forms, backfill around the footings, and clean up the site. The footing needs at least one week of curing before anything is built on top.

(415) 430-9873We submit the permit application to the City of Larkspur and coordinate the required pre-pour inspection as a standard part of every footing job. You never have to chase the building department yourself, and your project is on the record from day one - which matters when you go to sell.
Larkspur's expansive clay soil expands and contracts with every wet-dry cycle, and a footing that was not sized for that movement will show problems within a few years. We assess your soil conditions before we design the footing, not after the crew shows up. This is the single biggest factor separating a footing that holds for 30 years from one that starts to settle after the first rainy season.
Larkspur sits close to active fault systems, and California requires footings in this area to be reinforced with steel and connected with specific hardware to resist earthquake forces. We build to these requirements as standard practice - not as an upgrade. The pre-pour inspection by the city confirms this before the concrete is placed.
We serve Larkspur, Corte Madera, Mill Valley, San Anselmo, Tiburon, San Rafael, Fairfax, Novato, Sausalito, Richmond, Berkeley, and Albany. That coverage means we bring direct knowledge of local permit timelines, soil conditions, and inspection expectations to every job in your neighborhood.
Footing work is invisible once it is done, but it is what every deck post, addition column, and retaining wall depends on. We approach every footing job as if the whole structure depends on it - because it does. When you are ready to move forward, call us and we will schedule a site visit within one business day.
